Given the function f: x ⟼ 2x − 3, the inverse function is:
3x/2.
(x + 3)/2.
(x - 3)/2.
(x - 2)/2.
The function f is defined as R, the set of real numbers by f:x → 3x -2,
What is f⁻¹: x → :
(x-3)/2.
(x+3)/2.
(x+2)/3.
(x-2)/3.
For any function f, f⁻¹ always maps its:
Range to its domain.
Image to the range.
Domain to its range.
Domain to its codomain.
The arrow diagram in the figure shows the relationship between M and N.
The domain is:
{1, 4, 9, 8, 16}.
{1, 2, 3, 4}.
{1, 4, 3, 8, 16}.
{1, 4, 9, 16}.
Given that f:x → 2x + 5, then f(-3) gives:
3.
-1.
-3.
1.
